What else can I help you with?
Muscle is involuntary and has few mitochondria?
This statement is incorrect. Muscle tissue can be either voluntary (skeletal muscle) or involuntary (smooth and cardiac muscle). Additionally, muscle cells (myocytes) have numerous mitochondria to provide energy for muscle contractions.
What is the involuntary muscle action of alimentary canal?
Peristalsis is the involuntary muscle action of the alimentary canal. It involves wave-like contractions that push food along the digestive tract, allowing for the process of digestion and absorption to occur.
Which type of muscle CANNOT contract without being stimulated by the nervous system?
Cardiac muscle. Unlike skeletal and smooth muscle, the contraction of cardiac muscle is involuntary and requires stimulation from the nervous system. This ensures that the contractions of the heart are synchronized and coordinated.
Is the Golgi tendon tendon organ voluntary or involuntary?
To answer your question in brief, the Golgi tendon organ is an involuntary mechanism that serves to maintain muscle tension and prevent injury. They are groups of fibres that wrap around the tendon, and have type Ib receptors that relay activity back to your brain. Upon activation, they increase their activity, which forces the shut down of the muscle contraction in order to prevent tearing of the muscle from excessive activation.
Is the esophagus voluntary?
The esophagus is primarily controlled by involuntary muscle contractions called peristalsis, which moves food from the mouth to the stomach. However, we can control the movement of food voluntarily to some extent, such as during swallowing.
Is muscle tone the smallest amount of tautness or tension due to weak involuntary contractions of its motor units?
True
What is the maintenance of muscle tone in the wall of the blood vessels an example of?
Involuntary muscle contractions
Can A deficiency of calcium in the body can result in involuntary muscle contractions?
Yes it can
What causes shaking before a fever?
It is caused by involuntary muscle contractions.
A deficiency of parathyroid hormone can cause involuntary muscle contractions of a type called?
Tetany is the term for the muscle contractions that may be caused by hypoparathyroidism.
Series of involuntary muscle contractions along the walls of the digestive tract?
Peristalsis.
Involuntary muscle contractions that move the food through the digestive system?
peristalsis
A contraction in which there is no change in muscle length but there is a great increase in muscle tension is?
isometric contractions
Muscle is involuntary and has few mitochondria?
This statement is incorrect. Muscle tissue can be either voluntary (skeletal muscle) or involuntary (smooth and cardiac muscle). Additionally, muscle cells (myocytes) have numerous mitochondria to provide energy for muscle contractions.
What does a muscle relaxant do to help alleviate muscle tension or spasms?
A muscle relaxant works by targeting the nervous system to reduce muscle contractions, helping to alleviate muscle tension or spasms.
Are isotonic contractions often preceded by isometric contractions?
Isotonic contractions can be preceded by isometric contractions, especially during activities that require a gradual increase in muscle tension before movement occurs. In isometric contractions, muscles generate tension without changing length, which can stabilize joints and prepare the muscles for subsequent isotonic contractions, where the muscle shortens or lengthens while maintaining tension. However, isotonic contractions can also occur independently, depending on the specific movement and muscle activation patterns involved.
Why does eccentric produce more force than concentric?
Eccentric muscle contractions involve the lengthening of the muscle under tension, which allows for greater force production compared to concentric contractions where the muscle shortens. This occurs because the muscle fibers can generate more force during the controlled lengthening process in eccentric contractions, leading to greater tension development.
